+Changes 07/22/2014 Reformatted file to fit on Schematic.\r
\r
\r
1. [X] SW3 holes not big enough.\r
\r
2. [X] Is C26 rated at 25V in BOM? \r
C26 is 25V in schematic, 16V in BOM. \r
- OOPS! C23, C26, C40 & C46 should all be 25V. Will change database & BOM. Murata # GRM188R71E104KA01D, Digikey # 490-1524-1-ND, Part Def: CAP CER 0.1UF 25V 10% X7R 0603\r

07/08/2014 - RGB\r
\r
3. [X] LED8 takes up whole of pads so diff to solder \r
4. [X] Is CN3 a standard size? My DC plugs don't fit in it \r
2.5mm ID, 5.5mm OD Plug. CONN PWR PLUG DC 2.5X5.5 8A MOD Digikey # \r
CP3-002BH-ND \r
- This is probably most common size in USA. Same size as Raspberry PI, BeagleBone , SignaLink & others. RGB 07/15/2014\r

\r
5. [X] couldn't solder bottom pad of U5 by hand + hope it's OK \r
Attached to large gnd plane. Hard to solder. Designed for IR SMT \r
\r
7. [X] Would VDDA power supply circuit be better located closer to U1? \r
Data sheet advises placing caps on opposite side of board, under VDDA pins. \r
- Parts are place as close as possible, on same side of board. Return is low impedance plane and supply well bypassed. Unless this presents problems, I'd leave it. RGB 07/15/2014\r

\r
8. [X] Larger TAPR/Credits text on bottom? + there is plenty of room \r
- Enlarged text from 1mm to 1.42mm. Text now extends almost all the way across PCB. RGB 07/15/2014\r
+ Enlarged text from 1mm to 1.42mm. Text now extends almost all the way \r
+ across PCB. RGB 07/15/2014\r
\r
9. [X] What was Vin range meant to be? \r
- VIN is 1 diode drop lower than VEXT(6-16VDC) or approx 5.5 - 15.5VDC Used to power LM386 to get more output swing.\r
+ VIN is 1 diode drop lower than VEXT(6-16VDC) or approx 5.5 - 15.5VDC \r

\r
10. [X] move R20 label close to R20 + I loaded R20 in the wrong place! \r
R20 designation moved adjacent to part. RGB 07/15/2014\r
\r
11. [X] is 4k7 missing from BOM or just my order? + I didn't have any in my Digikey order \r
Part definition error. Part # in part definition field. Will correct database & BOM.\r
- This affects R2,R3, R4, R5 & R48. Should be Vishay Dale # CRCW06034K70FKEA, Digikey # 541-4.70KHCT-ND, Part Def: RES 4.70K OHM 1/10W 1% 0603 SMD 07/08/2014 - RGB\r

\r
12. [X] Re C26, could u pls align the BOM and sch? I'm not sure which one has to change. \r
C26 should be 25V to accommodate +16V power in max. \r
- OOPS! Found that C23, C26, C40 & C46 all should be 25V. That's why I made them separate line item. I'll Change BOM to Digikey part # 490-1524-6-ND Murata # GRM188R71E104KA01D\r

-13. [ ] Re CN3, Hmm, now I'm not sure! I dug around in the shed and found a connector that fits so I'm OK for now. \r
- CN3 is Switchcraft RASM712PX 2.5mm ID, 5.5mm OD Plug. CONN PWR PLUG DC 2.5X5.5 8A MOD Digikey # CP3-002BH-ND\r

I've noted a problem, but will wait til you decide. RGB\r
\r
-14. [X] OK I just check the BOM I have, and there are no 4.7k resistors on it, e.g. R2, R3, R4, R5. \r
- Part database error, invalid part definition. Digikey & Vishay Dale part numbers are correct. \r
- Part definition for R2, R3, R4, R5 & R48 should be: RES 4.70K OHM 1/10W 1% 0603 SMD Will correct part database & BOM.\r

R2, R3, R4, R5 & R48 now 4.70K 1/10W 1% 0603 parts in B2 revision. RGB 07/15/2014\r
\r
15. [X] CN7 3.5mm socket etc have two small plastic mounting lugs that require holes\r
- CN7, CN8, CN9 & CN10 plastic tabs interfere with pads on top layer. Since the tabs are plastic and don't extend thru the PCB, I am approving these 4 discrepancies. RGB 07/15.2014 \r

\r
16. [X] Should R46 be described as a trimmer resistor (rather than POT?) on the BOM\r
- R46 incorrectly specified on BOM. Corrected. Part s described as POT in DIGIKEY description. RGB 07/15/2014\r

17. [X] Is label for R1 & R2 transposed? \r
Labels were transposed. Corrected. RGB 07/15/2014\r
Added C48, 100nF cap across J5 to implement power up reset function. RGB 07/17/2014\r
\r
19. [X] replace J7 & J2 with 0805 0 ohm Rs\r
- Jumpers were originally inserted to permit bringing up SM1000 and protecting circuitry from overvoltages and measuring currents. \r
